The Flutter SDK image is ~2.8 GB and filled Docker Desktop's VM disk
("read-only file system" while extracting a layer). Build the web bundle
on the host instead and COPY client/app/build/web into the 2-stage
(NestJS build -> slim runtime) image. .dockerignore keeps the bundle,
drops the platform scaffolding. README documents the host `flutter build
web` prerequisite.

# The Flutter web bundle is built on the HOST (it needs a ~2.8 GB SDK image

# otherwise). Before `docker compose build`, run:
|
|
# (cd client/app && flutter build web --release)
|
|
# This Dockerfile just copies client/app/build/web into the runtime image.
